Hi,
There is no easy way to add votes and comments similar to the ones built in HikaShop for the product details page.
It would require extensive work in HikaShop to support that.
However, if you have an extension like JComments (
github.com/exstreme/Jcomments-4
), you can add such code at the bottom of the category / listing view file via the menu Display>Views to add JComments system to categories:
<?php
require_once (HIKASHOP_ROOT . 'components' . DS . 'com_jcomments' . DS . 'jcomments.php');
echo JComments::show($this->element->category_id, 'com_hikashop', $this->element->category_name);
?>
Different comments extension for Joomla will require a different piece of code. So you if you want to use another extension, you would have to check with the developer what code needs to be used for that integration.
